CHARLES W. WISE, OF PITTSBURGH, PENNSYLVANIA.

CELLULAR MEMBER FOR EGG-CASES.

Specification of Letters Patent.

Application filed March 17, 1913.

Patented Nov. 1 1, 1913.

Serial No. 754,906.

To all whom it may concern:

Be it known that I, CHARLEs W. lVIsn, a itizen of the United States ofAmerica, residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inCellular Members for Egg-Cases, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to foldable cellular members for use inconnection with egg cases, and the primary object of my invention is toprovide a light and durable fold.

able structure that can be advantageously used in connection with egg orother cases for transporting various kinds of merchandise by parcelspost.

A still further object of this invention is to provide a strong, durableand inexpensive foldable cellular member or collapsible partition orfiller that can be advantageously used in connection with a box forproviding a plurality of compartments in which eggs and other fragilemerchandise can be placed and safely transported by parcels post.

With the above and other objects in view the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein Figure 1 is aperspective view of a portion of a foldable box provided with theimproved foldable cellular member or partition. Fig. 2 is a perspectiveview of the member or partition partly collapsed.

In the drawing there is illustrated a collapsible cellular member orpartition comprising parallel longitudinal walls 1 having the upperedges thereof provided with equally spaced vertical slots or slits 2that are approximately half the depth of said longitudinal walls. Theendmost slots or slits are set in and removed from the ends of saidwalls, for a purpose that will presently appear.

Connecting the walls 1 are foldable transverse walls 3, said wallshaving the lower edges thereof provided with slots or slits 4approximately half the depth of said transverse walls. The walls 1 and 3correspond in depth, consequently the transverse walls 3 can be placedin engagement with the longitudinal walls 1 by interlocking said wallsat the slotted or slitted portions thereof. The upper and lower edges ofthe walls are then flush and said partition can occupy a horizontalposition in a box or inclosure 5 The transverse walls 3 are foldable, asat 6 at points intermediate the longitudinal walls 1 and the ends of thetransverse walls 3 protrude from the sides of the outer walls 1, wherebythe ends of the transverse walls will cooperate with the ends of thelongitudinal walls in spacing the compartments 7* of said partition fromthe walls of the box 5.

In order that the partition can be collapsed, with the transverse walls8 folded in between the longitudinal walls 1 it is necessary that one ofthe end transverse walls 3 have two folds the reverse of the other endtransverse wall and these folds have been designated A and B,distinguishing the same from the folds of the other end walls.

To prevent the intermediate folds of the end transverse walls fromprotruding beyond the ends of the longitudinal walls 1, the intermediatefolds are given an additional fold, as at C whereby the material of theend transverse walls will extend inwardly, as shown in Fig. 2. In otherwords, the end transverse walls have double folds between thecentralmost longitudinal walls and when the size of the partition isincreased beyond that shown in Fig. 2 every alternate space wouldaccommodate the double fold of end transverse walls.

A collapsible cellular member or partition in accordance with thisinvention can be used in connection with other boxes, receptacles orinclosures, other than that shown and disclosed, and I desire it to beunderstood that the collapsible partition can be made of any suitablematerial and of various sizes.

What I claim is A cellular member comprising a series of slottedlongitudinal walls and a series of slotted transverse walls interlockingwith the longitudinal walls, said transverse walls having folds betweensaid longitudinal walls whereby said longitudinal walls can be collapsedinto parallelism with respect to each other, the folds of the outerwalls of said series of transverse walls extending inwardly in oppositedirections with respect to each other, the intermediate portion of thelongitudinal Walls When the member is the outer transverse Walls of saidseries becollapsed. 10 ing provided With double folds, the double Intestimony whereof I afiix my signature folds of one outer transverseWall being opin the presence of two Witnesses.

positely disposed with respect to the double CHARLES W. WISE. fold ofthe other outer transverse walls, said Witnesses:

double folds providing means to prevent the J. P. APPLEMAN,

transverse Walls from protruding beyond MAX H. SROLOVITZ.
